ISQI ISTQB Certified Tester Advanced Level - Test Automation Engineering CTAL-TAE (Syllabus v2.0) Sample Questions:

1. Which of the following is the BEST example of how static analysis tools can help improve the test automation code quality in terms of security?

A) Static analysis tools can ensure there are no security vulnerabilities within test automation code
B) Static analysis tools can help detect the presence of repeated instances of code within test automation code
C) Static analysis tools can help detect hard-coded credentials that expose sensitive information within test automation code
D) Static analysis tools do not generate false positives when attempting to detect security vulnerabilities within test automation code

2. Some automated regression test scripts run by a TAS in a given test environment make calls to private APIs that require authentication for all requests (the authentication method is the same for all APIs). The SUT is a business-critical system. The following two changes are planned: a change in the authentication method of all APIs and a minor upgrade of the OS (Operating System) in the test environment. You have updated the test scripts to cope with the change in the API authentication method. Which of the following sequences of activities is BEST to ensure that the test scripts are not adversely affected by these changes?

A) First upgrade the OS, then implement the change in the API authentication method, and finally run all the updated test scripts
B) First implement the change in the API authentication method, then upgrade the OS, and finally run all the updated test scripts
C) Implement one change at a time and run a subset of the updated test scripts after each change
D) Implement one change at a time and run a subset of the updated test scripts after each change, and finally run all the updated test scripts

3. Automated tests run by a TAS on a SUT can be subject to sudden bursts of messages to log during their execution. All log messages that occur during execution must be permanently stored in the corresponding test execution logs by the TAS for later analysis. If logging is not performed correctly, these bursts can reduce the execution speed of these automated tests, causing them to produce unreliable results. Which of the following solutions would you expect to be MOST useful to address this issue for TAS logging?

A) Use a Network Time Protocol (NTP) server to ensure that the clocks of the machines running TAS and SUT are synchronized with a common time source
B) Avoid logging the messages that occur during the specified bursts to minimize any potential performance overhead in test execution
C) Log all the messages in memory using a circular buffer and periodically flush the buffer to the corresponding log files associated with the specific execution
D) Log all the messages directly on the corresponding log files associated with the specific execution to ensure the permanent storage of test execution logs

4. Consider a TAS aimed at implementing and running automated test scripts at the UI level on web apps. The TAS must support cross-browser compatibility for a variety of supported browsers, by ensuring that the same test script will run on such browsers in the same way without making any changes to it. This is achieved by introducing appropriate abstractions into the TAA for connection and interaction with different browsers.
Because of this, the TAS will be able to make direct calls to the supported browsers using each different browser's native support for automation. Which of the following SOLID principles was adopted?

A) Interface segregation principle
B) Open-closed principle
C) Liskov substitution principle
D) Dependency inversion principle

5. Consider a TAS implemented to perform automated testing on native mobile apps at the UI level, where the TAF implements a client-server architecture. The client runs on-premise and allows creation of automated test scripts using TAF libraries to recognize and interact with the app's UI objects. The server runs in the cloud as part of a PaaS service, receiving commands from the client, translating them into actions for the mobile device, and sending the results to the client. The cloud platform hosts several mobile devices dedicated for use by this TAS. The device on which to run test scripts/test suites is specified at run time. You are currently verifying whether the test automation environment and all other TAS/TAF components work correctly. Which of the following activities would you perform to achieve your goal?

A) Check whether all test scripts that will be executed by the TAS as part of a given test suite have expected results
B) Check whether the references to the device on which the given test scripts/test suites will be executed are correctly hard-coded within these test scripts/test suites
C) Check whether the TAF libraries that the test scripts will use to recognize and interact with the app's UI objects (widgets) function as expected
D) Manage the infrastructure that hosts the server, including hardware, software updates, and security patches
